Not that big, I made a deposit near to 5 BTC months before, lucky or no I managed to get around 10BTC.
For the ones who asked, yes, thank God I did won. After that day I NEVER played anymore.
Worse feeling I ever had it was think that I can lose all my BTC but if I decided to don’t bet higher I was accepting to loss around 75% of my whole bag.
Things escalated really fast. Scary, truly scary.
The main reason is to know the biggest streak, things has change since 2018, there is more casino who accept cryptocurrencies like XLM, RVN, DGB, so I gues your bankroll is “bigger” since the value of the coin is not that big.
5 BTC it's indeed a huge bankroll to started gambling, escpecially you were used martingale strategy. What was base bet did you use? 1 sat? Or did you reset your bet when the red streaks comes and then you bet bigger when you think it would be a green/win?
Fyi, freebitcoin has 5% House Edge, in a theory, you could have "more" red streak actually
